Three of Britain's Olympic mixed relay champions will compete in Japan: Alex Yee, who finished third in last year's WTC Series, 2020 winner Georgia Taylor-Brown and 2019 runner-up Jessica Learmonth.

Their gold medal-winning team-mate Jonny Brownlee, the 2012 world champion, will focus on the Leeds round on 11-12 June as he builds towards the Commonwealth Games in Birmingham later this year.

Elsewhere, Norway's Kristian Blummenfelt and Bermuda's Flora Duffy will be aiming to defend their world titles.

The World Triathlon Championship Series began in Yokohama on Saturday, 14 May and concludes in Abu Dhabi in November.

It’s a fantastic opportunity to see the very best in the sport, including Olympic, World and European champions.

With postponements and cancellations because of the Covid-19 pandemic in 2021, the final two events held last year in Hamburg and Abu Dhabi count as the opening two legs of the 2022 season.
